Abstract
Reliable multicast protocols can strongly simplify the design of
distributed applications. However, it is hard to sustain a high
multicast throughput when groups are large and heterogeneous. In an
attempt to overcome this limitation, previous work has focused on
weakening reliability properties. In this paper we introduce a
novel reliability model that exploits semantic knowledge to decide
in which specific conditions messages can be purged without
compromising application correctness. This model is based on the
concept of message obsolescence: A message becomes obsolete
when its content or purpose is overwritten by a subsequent message.
We show that message obsolescence can be expressed in a generic way
and can be used to configure the system to achieve higher multicast
throughput.
